Hypothesis based on Textual clues in the Temple Endowment
In the pre-1990 Endowment, there are two lines I'd like to point to as clues relating to a theory I have that the order of the Covenants in the Endowment has been switched around at some point in history:
ELOHIM: Jehovah, send down Peter, James and John and instruct them to give to the man Adam and his posterity in the Terrestrial world the law of consecration in connection with the law of the gospel and the law of sacrifice, and to cause them to receive it by covenant.
. . .
You will note the absence of mentioning the law of chastity, even though it has already been conferred at this point in the ceremony. My theory is that the original order of the Covenants put the law of consecration before the law of chastity, and that the law of vengeance was sandwiched in between them.
PETER: We are instructed to give unto you the law of consecration as contained in the book of Doctrine and Covenants, in connection with the law of the gospel and the law of sacrifice which you have already received.
This would make more sense, because the law of chastity would be directly connected with the token used for sealings.
What do you think? Many early exposes have things quite mixed up; so I don't know how well they can be relied upon as a reference in this matter.
